Moment-Preserving Modeling With Image Applications

July 6, 1998
Author(s)
Anastase Nakassis, Abdou S. Youssef
Linear least-square modeling is a powerful modeling approach. Optimal piece-wise constant modeling is an important special case. In this paper we will develop a piece-wise constant modeling method that preserves the regional means and regional first

Bootstrapping, autonomous testing, and initialization system for Si/Si$_x$Ge$_1-x}$ multi-quantum-dot devices

January 20, 2026
Author(s)
Tyler Kovach, Daniel Schug, Michael Wolfe, Evan MacQuarrie, Patrick Walsh, Jared Benson, Mark Friesen, Mark Eriksson, Justyna Zwolak
Semiconductor quantum dot (QD) devices have become central to advancements in spin-based quantum computing. However, the increasing complexity of modern QD devices makes calibration and control---particularly at elevated temperatures---a bottleneck to

Application of Voltage Controlled Crystal Oscillators to DC Voltage Reference Validation

April 8, 2025
Author(s)
Matthew Spidell, Malcolm White, Alan Jaffe, John Lehman, Gaylon Partain
DC voltage references are typically based on calibrated Zener Diodes which are subject to drift and therefore require periodic recalibration against a Primary Standard. Since it is preferable to maintain constant power to such references, the shipping and
